(Al-Insan) 76 : 2
إِنَّا خَلَقْنَا الْإِنْسَانَ مِنْ نُطْفَةٍ أَمْشَاجٍ نَبْتَلِيهِ فَجَعَلْنَاهُ سَمِيعًا بَصِيرًا

Indeed We have created man from a mingled ‘Nuthfa’ in order to trial him, so We blessed him with hearing and sight

Mingled ‘Nuthfa’ means the sperm of father and ovum of mother as mentioned in the verses 86: 5-7. The word Nuthfa is used for sperm as well as ovum. After staying 40 days in the womb of mother as ‘Nuthfa’- embryo, then 40 days as ‘Alaqa’- a clot and again 40 days as ‘Mudhu’gha’- clinging mass of flesh. Read together the verses 22: 5; 23: 12-14 and 32: 7-9. Prophet taught as an answer to a Jew’s question that, the bones and nerves are formed from the ‘Nuthfa’ of father, whereas blood and flesh are formed from the ‘Nuthfa’ of mother. If a man is compared to a computer, his body is the hardware, life is electricity and soul is the software. See the explanation 4: 1; 17: 36 and 29: 2-3 in the Splendid Book- the Three Times Knowledge.
